What is the function of Terminal Connector on the isolator? The Terminal Block is an important wiring device. With the development of technology, the terminal block has developed well. So what is the use of the terminal block in the isolator? At present, there are many isolated terminal blocks with CPU as the core on the market, with field programmable and communication functions, high flexibility, and can reduce inventory and fund backlog for customers. Terminal block is an accessory product used to realize Electrical Connection, which is industrially divided into the category of connectors. UK terminals are suitable for interconnection of a large number of wires. In the power industry, there are special terminal blocks and terminal boxes, all of which are terminal blocks, single-layer, double-layer, Electrical Connection, voltage, common, breakable, etc. . A certain crimping area is to ensure reliable contact and to ensure that sufficient current can pass. The terminal block is used to facilitate the connection of wires. It is actually a piece of metal sealed in insulating plastic. There are holes at both ends for inserting wires, and there are screws for fastening or loosening. For example, two wires, sometimes If they need to be connected, sometimes they need to be disconnected. At this time, they can be connected with terminals, and they can be disconnected at any time without having to weld them or twist them together, which is very convenient and quick. The isolated terminal block with CPU as the core will surely become the mainstream in this field. There is also a method of isolating the transmitter, where the sensor and transmitter are integrated and must be placed in a designated location. At this time, the isolation terminal is generally placed in the cabinet of the central control room, and the isolation terminal in the cabinet distributes power to the field transmitter. Which one to use depends on the PLC interface. During on-site commissioning, the interface between the instrument and the PLC may not match. The transmitting device is a four-wire transmitter with 4 ~ 20mA output, and the 4 ~ 20mA interface at the receiving end is a two-wire loop power supply. If connected directly, it will cause power supply conflict. The solution is to use the isolation terminal to receive and isolate 4 ~ 20 mA on site, install a special circuit in the output part of the isolation terminal, and match the PLC with a two-wire loop power supply interface. Therefore, there is also a very good application between the terminals on the isolator, which has attracted people's love.
